This invention relates to new and useful improvementsin h-ot water heatersuor furnaces and burners therefor; and has for its objects to provide aneicient burner and heater which willheat up quickly, which will `conserve the heat of the fuel and utilize all thereof and which may therefore be economically fuelled once each day, and which can be easily and economically constructed. A f urther object-.isv to provide such a device having storage both for heat and water.

These yobjects are accomplished by providing a plurality of annular water legs depending Yfrom* acommon dome or head, the

outer of suchlegs extending downward and surrounding the ire chamber; and by providing in this chamber an efficient type of gas heater or burner so designed as to conserve' the heat and deliver same to the water storage tinguished, as will readilybe understoodfrom the following specification onv reference `to the accompanying drawings,j1n which:

Fig. 1, is a vertical sectional elevation` taken substantially on the center line;

Fig. 2, is a horizontal section taken as on the line II-II of F ig. 1;

Fig. 3, a similar section taken as on the line III-III; and y 3o gure. Y

Referrin@r now to the drawings t-he heater in its prefterred form comprises three an'- from the common water chamber 13. vThe outer water leg 10 extends downward'to the bottom of the tire chamber 14 and forms the outer wall thereof, this leg rests on a base 15,'

preferably a cylindrical concrete pier extending upward from the floor level 16. Preferably also the outer water leg 1s entirely'surmaterial 17, preferably asbestos, which may be retained if it beso desired by a metal shell 18. The two inner water legs 'extend only part-ially asfar down as the outer leg, the' inner leg being shortest, so that an annular combustion chamber 1s formed havingv a chambers after ktheA heating flame is ex F ig. 4, also a similar section of the burner only, taken as on the line IV-IV of the same ou'tlet pipe for hot water. pipe.v 3 3 isa safety valve.V nular water legs 10, 11 and 12 which depend posed directly below the' coal stepped crown from the center of which a Hue 19y extends upward'through the center of the waterchamber 13 terminating slightly above the dome 20, lwhich' forms the top of such chamber.A Disposed on thisy extension 21 is va T 22 having a horizontally extending portion 23 `which leads to theusual wall or chimney flue. 211 is a damper land 25 a cap closing the upper'end of the T 22. It will of course be understoodthat this flue may extend straight upward' if preferred and the .damper be located in such verticalflue. The horizontal flue 23 shown, may of course be turned in any direction desired so as to lead to a'ilue in any position. f

Each water leg is formed by a pair of concentric annular shells joined at the bottom, and the adjacent shells of each pair of water legs as 10 and 11 are similarly joined at their upper end.

In orderto avoid chance of dead air spaces betweenthe upper ends of the water legsA a tube 26 is extended through the water leg 12 adj acentjthe upper end thereof and a similar tube' 27 through the water leg 11, in similar location, the two H tubes preferably being ,axially aligned. A' third tube 28 may be extended through t'he water legy 10 and the insulation"17rtherearound in alignment with 4thetu'bes 23 and 27 thesetubes providing a clean-out or inspectiontube-` 29 is a hinged door closing the outerV end of the tube 28.'y 30 yisan'inlet pipe for cold water and 31 an 32 is a drawof is closed by a/hinged ldoor 35. This door serves ,as a coalV door, should it be desired to heat lthefuriia'ce with coal. 36 is a similar butfprefer'ably largeriopning ordinarily disj opening. This Qopeningis 'closed ,by a door 37 and where rounded by an annular layer of insulatingr 'e with gas. such event, 1 prefer 'to use a 4burner 'of improved type, 'preferably circular in horizontal section and preferably having a base 2whichis aquadrant of a circ cular plate. From the lradial edges ofeach of 'these quadrants' vertical walls 43, 114. ex-

tend upward. Circular walls 39 which arch over at the top complete with the base of these Walls gas chambers kinto which gas is delivered by the gas pipes 46, 47, 48 and 49. These pipes are controlled by individual valves 50, 51, 52 and 53 respectively. Intermediate the height ot the walls l5 quadrant shaped plates 54 extend outward and from these plates radial extensions 55, 56 of the walls 42, la extend upward. Circular outer walls 57, and quadrant shaped top walls 58 complete the enclosure.

The completed units assembled, form la dome shaped gas chamber divided into segregated chambers byradial walls.

From the gas chambers'i'ornied by the enclosing walls 43, lil and Ll5 a plurality of tubes 59 extend radially outward and project through the outer walls 57 forming burner nozzles. These tubes 59 are in successively higher banks which incline upward atprogressively higher angles, the last banlr 60 extending substantially vertically upward and projecting` through the top plates 58. rIhe space between these tubes is preferably lilled with asbestos fiber 6l. Each of the gas chambers is provided with an air inlet G2 which is regulated by an external slide 63, which may be in additionto usual air mixing devices on Athe pipes themselves.

The purpose of subdividing the burner i into quadrants is threefold, iirst; ,in order that the amount ot gas to be lighted at one time be reduced; second; in order that the various sections may be introduced through the ash door opening; and'third, thaty one or more sections may be turned out after the water is hot. It lwill therefore be understood n that the burner may be made in a single piece,

if so desired, and also,'that the number of subdivisions into individual units, or the number of Asubdivisions of an integral-unit may be more or less than the number shown.

It will be further understood that the burner may be of any desired size or shape.

In using the heater it is filled withl water in the usual manner through the pipe 30 from a suitable Vsource of supply not shown. Gras may then be turned through one of the O'as vsupply pipes into a section ot' the burner and this be lighted, after which additional sections inay be lighted in succession.V The heat of the combustion ythus etected is directed by the individual gas pipes against the various water cells and as the amount Voi: water in each is restricted in quantity, they will rapidly heat it up. At the same time', the asbestos packing around these burner tubes will also be heated lso that a storage supply of heat will be set up in the burner itself, andVV ,such heat will be conserved in order that after the gas is turned oli and combustion ceases the burner `will radiate-heat to kmaintain the water nin heated condition.y

It will `course be understood that the heater may be used as a coal heater by simply removing the gas burner and building a coal tire in the furnace. Such tire may be replenished by putting coal in through the coal door and may be partially banked by placing ashes and cinders through the clean-out door.

It will further be understood that the usual types of the thermostat or other heat control devices may be used where gas is the fuel.

Having described my invention, what I claim isp..

l. A gas burner Jfor a hot water heater and heat conserving system, including a dome shaped shell, radial walls dividing said shell into a plurality ot' segregated gas chambers, said radial walls extending beyond said shell, an enclosing shellv spaced from said first shell, a plurality of pipes torming'burner nozzles extending from said `chambers beyond said enclosing'shell, a heat conserving medium disposed between'said shells and surrounding said nozzlesV and means tor supplying gas and air to said gas chambers. l

2. A gas burner for a hot Water heater and heatV conserving systemfineluding a segment ot a domeshaped shell, radial walls forming with said shell a segmental gas chamber, said radial walls extending beyond vsaid shell, an enclosing segmental shell spaced from said lirst shell, a plurality of tubes forming burner nozzles extending from said chamber beyond said enclosingshell, a heat conserving medium disposedbetween said shells and surrounding said tubes, and means :tor supplying gas and air to said gas chamber.
